Fireproof porcelain ball is fireproof the ball is with industry alumina and fireproof kaolin are main raw material, become via scientific recipe, figuration and fire of high temperature forge.
1.Mechanical intensity is high, use cycle grows;
2. chemical stability is good, do not produce chemical reaction; with stock
3.High temperature resistant performance is good, highest heat-resisting temperature can achieve fireproof porcelain ball 1900 degrees. Special apply to fertilizer plant discretion lukewarm commutation furnace, in changing furnace of alkylation of chamfer of converter of furnace, hydrogenation, to decoke and armour, fluid is enraged dispersedly since, prop up, the action that enclothe and protects activator. The hot-blast stove that fireproof porcelain ball also can use at steely industry and heat in shift device. The main problem that uses fireproof ball to encounter at present is, fast aluminous fireproof ball because its hardness is tall, brittleness is big also, dry grind cause bumpy of surface of stone of ball stone craze, ball easily, cause the appearance with very tall wear and tear thereby, can use the method that polishing has to ball stone before leaving factory only now, the ball stone with winkle craze or tall wear and tear.
Fireproof ball, basically have the effect such as accumulation of heat. The wind force of intromit regenerator is delivered through the heat of regenerator, temperature rises a few Baidu to get on 1000 degrees even suddenly. Bulbiform matrix has thermal shock stability big, intensity cleans quantity of heat of good, harbour high, easily, but the advantage such as repeated usage.
Numerous spherule breaks up air current very small stream, air current is in matrix midstream outdated, form strong turbulent flow, broke through matrix surface effectively add facing, because ball way is very small, conduct radius small, thermal resistance small, density tall, thermal conductivity is good, reason can realize burner of type of accumulation of heat frequent and the requirement of fast inverting.
Matrix can use 20~30 second / the inverting of H, air current of high temperature smoke via matrix bed can fall flue gas to be discharged to 130 ℃ left and right sides inside layer hind. High temperature is gas be in with matrix of classics of empty air current warm-up can part to arrive to compare flue gas temperature only inside diameter of go the same way low 100 ℃ left and right sides, temperature efficiency is as high as 90% above. Because matrix bulk is very cabinet, the throughput capacity of bed of together with spherule is strong, although accumulate the obstruction after ash,increase to also do not affect heat to trade index.
Fireproof ball basically is used at metallurgy industry hot-blast stove harbour can the fireproof ball that accumulation of heat uses. Have purity, high strength stability of big, thermal shock is good, service life is long wait for an advantage.
How to differentiate are manual and fireproof ball and mechanism fireproof ball? Manual and fireproof ball and mechanism fireproof ball is by differ two kinds completely the fireproof ball that producer type production comes out, fireproof ball and firebrick produce the mechanism technology is roughly same, manual and fireproof ball is different however, its can distinguish from the following respects:
1, will differentiate from the exterior the mechanism is fireproof ball and manual and fireproof ball, following plan institute are shown.
Manual and fireproof ball and mechanism are fireproof of the ball discern
Through on the picture looks two kinds of fireproof balls, can see the mechanism is fireproof apparently ball, have line of 3 circles link, when the machine that control a ball undertakes machine pressing, this is formed, and manual and fireproof ball is done not have.
2, from outside exquisite, smooth pitch will discern; Manual and fireproof ball is to use clay to serve as adhesive, and the mechanism is fireproof the ball is to use yellow artificial gum commonly or lignin undertakes agglutinate, its are more smoother than the surface of manual and fireproof ball, exquisite.
3, will discern from the quantity that contain aluminium and compression intensity. The mechanism is fireproof no matter the ball is the quantity that contain aluminium or compression intensity should compare manual and fireproof ball to be gotten high much.
4, will discern from fireproof ball price, the mechanism is usually fireproof price of more fireproof than common handiwork ball wants the ball hundreds of tall Qian Zun is right, the scarcely with so a lot of lower price is normal, especially business is very much recently the mechanism of the holiday that make is fireproof ball, on the exterior very fireproof like the mechanism ball, and each index is a lot of wronger however. Hope the friend that purchase must notice.
Fireproof ball is with industry alumina and fireproof kaolin are main raw material, become via scientific recipe, figuration and fire of high temperature forge, highest heat-resisting temperature can achieve fireproof porcelain ball 1900 degrees.
Fireproof porcelain ball divides common and fireproof ball and fast aluminous fireproof ball, common and fireproof ball is applied to vitriolic the converter with fertilizer industry and commutation furnace, the hot-blast stove that fast aluminous fireproof ball applies to the industry such as urea, iron and steel, heat the equipment such as commutation furnace. Apply to fertilizer plant discretion lukewarm commutation furnace, in changing chamfer of converter of furnace, hydrogenation, to decoke and armour alkylation furnace, fluid is enraged dispersedly since, prop up, the action that enclothe and protects activator. The hot-blast stove that fireproof ball also can use at steely industry and heat in shift device.
Fireproof ball is applied to vitriolic the converter with fertilizer industry and commutation furnace, the hot-blast stove that fast aluminous fireproof ball applies to the industry such as urea, iron and steel, heat the equipment such as commutation furnace.
[ball of accumulation of heat explains: ] ball of accumulation of heat weighs bulbiform matrix again, bulbiform matrix has thermal shock stability big, intensity cleans quantity of heat of good, harbour high, easily, but the advantage such as repeated usage. The system of combustion of ball of accumulation of heat that applies to gas and furnace of industry of blame gas fuel is chosen.
[: of characteristic of ball of accumulation of heat? The spherule of efficient accumulation of heat that our company produce? , the area that compare a list can achieve 240m2/m3. Numerous spherule breaks up air current very small stream, air current is in matrix midstream outdated, form strong turbulent flow, broke through matrix surface effectively add facing, because ball way is very small, conduct radius small, thermal resistance small, density tall, thermal conductivity is good, reason can realize burner of type of accumulation of heat frequent and the requirement of fast inverting. Matrix can use 20~30 second / the inverting of H, air current of high temperature smoke via matrix bed can fall flue gas to be discharged to 130 ℃ left and right sides inside layer hind. High temperature is gas be in with matrix of classics of empty air current warm-up can part to arrive to compare flue gas temperature only inside diameter of go the same way low 100 ℃ left and right sides, temperature efficiency is as high as 90% above. Because matrix bulk is very cabinet, the throughput capacity of bed of together with spherule is strong, although accumulate the obstruction after ash,increase to also do not affect heat to trade index. Spherule of accumulation of heat is had fight the characteristic with the oxidation, strong sex that fight broken bits. Of spherule of pottery and porcelain change, clean very convenient, can repeat use.
[norms of ball of accumulation of heat: ] Φ5mm Φ8mm Φ10mm Φ16mm Φ18mm Φ20mm Φ25mm Φ30mm
[material of ball of accumulation of heat is qualitative: ] tall aluminium qualitative, corundum zirconium corundum is qualitative, qualitative.
